Method for producing foamed shoe in mold

Abstract

The present invention provides the production process of mold foamed shoe in high production speed and low cost. The production process includes the step of setting material to be foamed inside mold; the step of foaming inside the mold; the step of cooling; and the step of forming the semi-finished shoe product. The production process can produce semi-finished shoe product in high speed and low cost, has 85 % of the foamed material set inside the mold to produce high vamp shoe sole.

Description

technical field [0001] The invention relates to a production technology in the process of manufacturing and processing shoe soles, in particular to a method for manufacturing in-mold foamed shoes. Background technique [0002] At present, in the manufacturing process of the general shoe material production industry, the most troublesome problem for the production and processing personnel is that the steps of shoe material foaming processing and manufacturing are too complicated, and the various machines necessary for foaming production are very diverse, and the operation of precision machines is very Time-consuming, labor-intensive, and wasteful, often make the production efficiency of shoe material manufacturing unable to be improved, and relatively cause the problem of high production costs; therefore, it is currently necessary to seek a manufacturing method that can quickly produce shoe materials and save costs. One of the important issues in the industry. [0003] Among...

Problems solved by technology

[0010] This method has been used in the industry for a long time, but there are still problems that cannot be solved in the above-mentioned manufacturing method:

[0011] One, in the commonly used foaming manufacturing method of shoe materials, it is necessary to use step (1) to make raw materials into substrates (such as plates, columns and blocks), and then make the substrates through step (2) to make them meet the requirements of the oven. The size required for foaming and shaping is finally foamed into a semi-finished product with the cooperation of steps (3) and (4). Therefore, this commonly used shoe material foaming manufacturing method still needs to go through a heating and cooling process after foaming. The second cooling step, and the above-mentioned production process requires the use of more molds and machinery, resulting in high cost and complicated steps for this production method;

[0012] Second, the commonly used shoe material foam manufacturing method needs to use six manufacturing steps, and the operation time of step (3) is as long as four hours (hr), so the production time of this commonly used shoe material foam manufacturing method is too long , will also cause waste in production costs;

[0013] Its three, because the foam material of this kind of manufacturing method needs to pass through step (5) blank material is made into the size when conforming to shoe material design, so can produce a large amount of waste materials in step (5) (the waste material that chops has about 20 %), forcing manufacturers to increase equipment for recycling waste operations (another cost waste);

[0014] Its four, because commonly used shoe materials generally all can pass through step (5), cause sole 50 will be cut into straight slices 51 (see figure 2 As shown), the general semi-finished shoe material cannot be simultaneously produced in the process of shoe foam molding with high side wall soles (or soles with peripheral shapes), and additional processing and production steps for high side walls and peripheral shapes must be added to form The problems of cost increase and complicated processing; the above-mentioned content is the problem that shoe material mold manufacturing developers and shoe material manufacturers most want to overcome
